Complete Surgical Enucleation of a Giant Chylous Mesenteric Cyst

Abstract

Mesenteric cysts are rare benign abdominal tumors, and they can appear anywhere in the mesentery of the gastrointestinal tract, from the duodenum to the rectum. They are generally asymptomatic and may present as an incidental finding. The diagnosis is confirmed by the laparotomy findings and the results of the histopathological examination. Complete surgical (open or laparoscopic) enucleation of the cyst is the treatment of choice. We present a case of a female patient who presented with abdominal pain and a giant palpable abdominal mass. The patient underwent a surgical exploration which showed a giant mesenteric cyst. A complete surgical enucleation of the cyst was successfully performed without the need of bowel resection. The histopathological examination of the cyst was compatible with the diagnosis of chylous mesenteric cyst.

Chylous content might determine the optimal surgical approach for mesenteric lymphatic malformations in childhood

“…Some investigators have reported the successful excision of mesenteric LMs with chylous content without bowel resection in adults. 19,20 We believe that in these adult cases, the chylous cysts might have originated from a leak directly from the mesentery as an acquired chylous cyst and not, such as occurs in pediatric patients, from an error occurring during embryologic development. Therefore, the intestinal loops were probably not involved, justifying cyst removal without bowel resection.…”

Eight-Kilogramme Giant Mesenteric Cyst of Mullerian Origin: Case Report and Review of Literature

“…Beahrs et al reported four main aetiologies of mesenteric cysts: developmental (enteric, urogenital, lymphoid and dermoid), infective (mycotic, tuberculous or parasitic) traumatic and neoplastic 5 . Mesenteric cysts can also be classi ed according to their histopathological ndings into six groups: lymphatic origin (simple lymphatic cysts and lymphangiomas), mesothelial origin (simple mesothelial cysts, benign cystic mesotheliomas and malignant cystic mesotheliomas), enteric origin (enteric cysts and enteric duplication cysts), urogenital origin, mature cystic teratomas (dermoid cysts) and non-pancreatic pseudocysts (of traumatic or infectious origin) 12,14 .…”

Chylo-lymphatic mesenteric cyst in a 7-year-old

“…Mesenteric cysts are rare benign pathologic entities with an incidence of 1:100,000 in adults and 1:20,000 in pediatric hospital admissions (1). The anatomical location is along the root of the mesentery, beginning from the duodeno-jejunal junction up to the rectum.…”
